VERMONT, A CORPORATION OF VERMONT ANTIRAIL SPREADER FOR TRACK SCALES Application filed .Tune 7, 1928. Serial No. 283,582.

This invention relates to improvements in heavy-duty scales and more particularly to heavy-duty scales of the type employed for weighing railroad cars, commonly known as railway track scales.

The principal object of this invention is the provision in a scale of the class referred to of an inexpensive and efficient device for preventing undesirable horizontal movement, or spreading, of the rails, such as is caused by running heavy loads onto the scales. I

Other objects of the invention, together with certain details of construction and combinations of parts, will be more particularly described by reference to the accompanying drawings and pointed out in the appended claims.

In the drawings:

Figure 1 is a transverse cross-sectional view of the track scale, the scale levers being omitted;

Figure 2 is an enlarged view of a portion of the mechanism shown in Figure l; and

Figure 3 is a cross-sectional viewtaken on line 33 in Figure 2.

Similar characters of reference indicate corresponding parts throughout the several views of the-drawings.

Referring to the drawings wherein the preferred embodiment of the invention is set forth there is shown a scale pit generally indicated by the reference character 10. A deck 11 covers the pit, the deck being higher in the middle than at each end to provide an effective water shed. The deck is provided with a plurality of suitable openings through which project rail stands 12 rigidly secured to cross-beam 13, which is adapted to rest on the main scale girders (not shown), by any suitable means, as bolts 14 and nuts 15.

The rail stands support rails 16 which are securely attached to said rail stands by means of rail clips 17 as is well understood in the art.

To the inner sides of heads 18 of the rail stands 12 are rigidly fastened by means of bolts 19 and nuts 19 the brackets 20. Integral with each of said brackets 20 are a pair of apertured projections 21 adapted to form clevises, in the apertures of which are mounted pins 22 suitably retained in position by means of cotter pins 23. A tie bar 24 is pivotally mounted on said pins and of a length suflicient to maintain the rails the standard distance apart.

Angle plates 25 are preferably bolted to the deck 11, said angle plates having upstanding flanges 26 which cooperate with the heads 18 of the rail stands to provide a weather and dirt shield for preventing water, ashes and other foreign matter from dropping onto the scale mechanism, whereby the operation of the scale would be hampered and the accuracy impaired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patentof the United States, is:

1. In a track scale, the combination with a plurality of rail stands having rails sup- 7 ported thereon, of a means pivotally connected to said rail stands comprising tie bars connecting said rail stands and mounted on pivot pins carried by the'said rail stands, whereby said rails are prevented from spreading when a heavy load is run onto said scale.

2. In a track scale, in combination, a plurality of spaced rail stands, rails supported thereon, brackets mounted on said rail stands, and a tie bar pivotally attached to said brackets on pivot pins disposed in spaced projections extending from the said rail stands.

3. In a track scale, in combination, a plurality of spaced rail stands, rails supported thereon, brackets mounted on said rail stands, said brackets having clevises thereon and a tie bar pivotally attached to said clevises.

4. In a track scale, the combination with a plurality of rail stands having rails supported thereon, of a means comprising tie bars, pivotally connected to inwardly eXtend- 95 ing arms of brackets attached to the heads of the said rail stands, whereby the said rails are prevented from spreading when a heavy load is run onto said scale.

5. In a track scale, in combination, a plurulity of spaced rail stands rails supported thereon, brackets mounted on said rail stands, and tie bars pivotally attached to horizontally disposed, spaced arms, whereby the said rails are prevented from spreading.

In testimony whereof, I have hereunto set my hand.

ALFRED BOUS'FIELD.
